Abstract
A system and method for detecting faulty engine anti-ice sensor is disclosed and may include obtaining first pressure data representing a first pressure over a period of time at a first engine anti-ice pressure sensor on an aircraft engine. The method may further include obtaining second pressure data representing a second pressure over the period of time at a second engine anti-ice pressure sensor on the aircraft engine. The method may also include generating a variance value based at least partially on a variance of a difference between the first pressure data and the second pressure data. The method may include providing an indication that liquid is within the first engine anti-ice pressure sensor or the second engine anti-ice pressure sensor when the variance value exceeds a threshold.
